GEORGE KNEUPER, OF N EV YORK, N. Y.

ATOMIZER.

SPECIFICATION forming part of Letters Patent No. 394,775, dated December18, 1888.

Application filed March 2, 1888. Serial No. 265,975. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE KNEUPER, of the city and county of New York,in the State of New York, have invented a new and useful Improvement inAtomizers, of which the following is a speciiication.

I will describe an atomizer embodying my improvement in detail, and thenpoint out the novel features in the claims.

In the accompanying drawings, Figure l is an elevation, nearly all insection, of au atomizer embodyingl my invention. Fig. 2 is alongitudinal section, upon a larger scale, of the end portion or sectionof the air and liquid tubes; and Figs. 3 and if are sectional. views,upon the same scale as Fig. 2, of the parts forming the tip portions ofsuch tubes detached from each other.

Similar letters of reference designate corresponding parts in all theiigures.

A designates the liquid-receiver, and B O designate, respectively, theair and liquid tubes surmountiug the saine. I have here shown aliquid-receiver made wholly of soft indiarubber, like that shown in ,myLetters Patent No. 363,247, dated May 17, ISST; but in so far as myinvention relates to the tubes B O or their attachments, the receiver Amight be of rigid material, as glass.

rlhe air tube B has a soft-rubber or 'other bushing or stopper portion,h, which fits snugly into the mouth of the liquid-receiver A, and theair-tube is terminated by a cap, B', having a perforation, h', throughwhich the spray is discharged.

The liquid-tube C terminates ina liquidnozzle, C', from the end of whicha stream of liquid is forced by the air-pressure within the receiver A.The liquid-nozzle O, although made independently of the liquid-tube, isyet permanently secured thereto.

In the usual construction of atomizer the entire air-tube B, clear tothe perforated cap B', is made of one piece, in which the liquidnozzle Cis fixed and-non-adjustable; but I employ a tip-section, B2, which ismade separate from and secured to the tube B. I have here shown thetip-section B2 as secured by a screw-joint, bso that it may be detached.The tube-section B2 constitutes in effect a portion of the air-tube.

The liquid-nozzle C is screwed intoa bore, b3, in the tip-section B2,and has longitudinal grooves c, or its outer wall cut away to formpassages through which the air may escape past the liquid-nozzle C.

By the compression of the hand on the liquid-receiver A apressure df airis brought to bear on the top of the liquid in said receiver, and theliquid is forced up the liquidtube O and through the liquid-nozzle O',

andat the same time the compressed air which passes upward through theair-tube B around the liquid-tube C passes through the passages c, andcatching up the liquid from the nozzle C', discharges it in spraythrough the perforations in the cap B.

To provide for varying the character of the spray, I adjust theliquid-nozzle in the bore b3, so that it will project more or lessnearly to the cap B. If adjusted into contact with the cap B, anapproximately solid stream will be thrown, and if adjusted back to aboutthe position shown in Fig. 2 an effective spray will be thrown.

Inasmuch as the liquid-tube C is of soft indiarubber it will readilyturn in the bent tube B to permit the liquid-nozzle C to be adjusted,and the tube B may be of metal and bent before the tube O is insertedinto it. The liquidnozzle C may, if desired, be of silver, and then theliquid, even if it be of a corrosive character, will not come in contactwith the air-tube B or with any other metal save with the liquid-nozzleC', if that be made of silver rather than hard india-rubber.

It will be understood that several tips B are commonly interchangeablyfitted in place and may be substituted one for another as it may bedesired to use one or the other tip for the locality which it is desiredto treat-as the larynx, the nasal passages, the ear, &c.

lVhen the rubber liquid-receiver A is coinpressed, air is caused toexert its pressure on the liquid, and is also forced up the tube B, andwhen the liquid-receiver is released and allowed to recover air passesin through the valve d, which is arranged in a branch, b4, at the sideof the tube B.

Yhen the atomizer is operated simply vby compressing the liquid-receiverA, it is difficult in some cases to prevent the nozzle from IOOwavering; and to hold it steadyninless Sonie Special means are providedilor the purpose, l therefore provide a hand-piece, or, as l terni it, aSpooin D, oi' metal or oi hard material, which lies closely 13o the wallof the .receiver A and eonfornfls to the shape of the bulb or receiverin a vertical plane. AS here represented, this spoon or hand-piece D isformed of a piece of Sheet metal, and in one piece with flanges or a boxwhich neloses the braneh 1), and is secured by Screws lf to the tube l.Obviously the spoon or hand-piece D might be otherwise formed andsecured in plaee, and its only requisite is that it shall lie closely tothe normal contour of the liquid-reeeiver A, as Shown.

To use the deviee, the liquid bulb or reeeiver A is grasped in the handwith the spoon or lmnd-pieee D lying' against the palm of the hand, andthen when the bulb 'is Compressed by the fingers thel aloinizer will beoperated and the nozzle held with comparative steadiness and preventedfrom wavering' or moving', and therefore the spray may be directed withproper Meuraev against one spoi, as in the throat.

\Vhat I elaliin as my invention, and desire to Secure by Letters Patent,is-

l. The eoinbinatiini, with a liquid-reeeiver and an air-tube providedwith a tip-section made Separate li'roni the tube and detaehabl)Y joinedthereto, of an inner liquid-tube within the air-tube and a liquid-nozzleon said liquidtube, itted lo and adjustable lmigthwise in the tipseetionand havingl air-passages in its exterior, substantially as hereindeserillied.

The combination, with the air andliquid tubes of an atomizer and aliquid-receiver formed oii' soft india-rubber, of a rigid spoon orhand-piece, as l), which lies` closely to ihe receiver and 'foi-n11 arest for the palm olf the hand in compressing ihe reeeiver, substalvtiallv as herein deseriliied.
